' VEHICLE HEADLIGHT.

Application filed November 5, 1923. Serial No. 672,899.

T all whom it may concern:

c it known that I, DANIEL U. DOZIER,

a citizen of the United States, residing at Norfolk, in the county ofNorfolk and State of Virginia, have invented certain new and usefulImprovements in Vehicle Headlights, of which the following is aspecificat-ion.

My invention relates to vehicle headlights.

The object of the invention is toprovide an efiicient headlight forautomobiles which contains advantageous features which will be morefully described herein and specifically pointed out in the claimshereunto annexed recourse being had to the accompanying drawing forminga part of this specification in which Figure 1 is a sectional view ofone form of my device taken on the line 1 in Figure 2.

Figure 2 is a front view.

Figure 3 is a rear view.

Figure 1 is a front view detached from the incandescent lamp.

Figure 5 is a plan of my device removed from the lamp. 7

Figure 6 is a plan of the colored light transmitting are shaped plate.

Figures 7, 8 and 9am elevations of modified forms of shades.

Figure 10 is a sectional view of a modified v form of half shade or lampcover.

Figure 11 is a sectional view of a reflector of a headlight showing themanner of distributing the rays of light from my device.

Figure 12 is a front view of the same.

In the drawing like reference numerals indicate similar parts in all theseveral views 1 represents an elevation of an incandes cent lamp usedfor headlights of automobiles and is provided with a base 2 fitting intothe socket 8. in the ordinary manner.

4: is a shellor half shade having a straight or horizontal front portionand a rounded rear portion, as shown in Figure 1, while in Figure 10, Ishow a modified form 5 wherein the. whole shade is semi-elliptical andwhich will be described hereafter.

6 is an orifice which partly surrounds the lamp base 2.

7 is a circular shaped spring soldered, or otherwise fastened to theinner rear portion of the shade 4 or 5 and is adapted to have a springfit over the base 2 to hold the shade in place upon the lamp.

To further support the shade and allow for the insertion of any sizelamp, I provide a spring or springs 8 extending across the diameter ofthe shade, from side to side, as at 9, and located under the lamp 1 asshown in Figures 1, 2 and 10 thereby holding it in a yieldable mannerand capable of being distended according to the size of the lamp whichis inserted over the spring until the spring 7 engages the lamp base 2.

10 is a slot placed in the top of the shade 4.- or 5 and extends, withdecreasing width. about two thirds of its circumference and is shapedlike a segment of a circle formed by a chord and the are of a circle.

Over the opening 10 I place a curved glass or nica plate 11 of one. ortwo colors, for example, one. red portion 12 and a green portion 13,Figure 6, for emitting a crescent shaped glow on the head lightreflector 'and lens, as shown in Figures 11 and 12,

also for causing different colored rays to be cast upwards or at anangle as will be described hereafter.

The glass plate 11 may be of even width throughout or have reduced ends11 if desired, shown in Figure 6. The plate 11 is inserted under theispring tongues 14 and pushed towards the rear of the shell or shade 4cor 5 until its outer edge slips below the projection 15 which holds itin place. If the glass 11 is divided into two colors or perhaps threecolors, it may be moved so that any color may be used, if desired.

16 is a narrow strip formed with the shade 4e and terminates with thedisc or plate 17 and is for the purpose of shading the direct rays fromthe source of light, as in Figure 2, while in Figure 10 I make the shadeso that its outer edge will extend a little below the horizontal centreline 18 of the lamp 1.

19 is a depression which forms a knob on the inside of the shade 5,Figure 10, and is for the purpose of resting upon the upper part of thelamp and assists in keeping it in place and allowing for an aircirculating space for keeping the shell or shade cool.

In Figure 1, 20 represents, by dotted or broken lines, the location of apossible side opening in the shell 4 or 5, and 21 are similar linesshowing an apronfor further shading the light'if it is desired to usesuch.

In Figure 9 I show an inclined light defleeting shade having an angle 22of approximately 76 degrees. I also show the top of the shade perforatedat 23 arranged to form a shape like that at 10 and occupyingapproximately the same area.

In Figures lland 12 I show my invention within the reflector of aheadlight, as at 24, showing the reflection of the rays in the ordinarymanner, the arrows 26 indicating the upward or angular rays through theglass 11 passing through a suitable orifice 1n the top of the reflector,as at 25, though my device may be used without'the reflector 24, ifdesired.

The colored rays through the glass 11 are thrownat an angle ahead oftheautomobile and if the tail lamp should go out, a following car drivermay see them and would identify fire apparatus if so equipped as well asordinary automobiles. The shape of the slot 10 covers a part of thereflector 24 with a crescent shaped light area, as at 25 in Figure 12,and if suitable marks or letters are placed on the plate 11, they wouldbe visible in a magnified manner upon the reflector. In this manner, onecar may be distinguished 'from another by properidentifying marks.

My device may be arranged so that the light may be thrown to the rightor leftacting also as a light diffuser and the colored rays are sodistributed that the will be raised so as to bedistinguished above thebright lights of oncomingcars and preventblinding.

My invention can be used in headlights having ordinary cheap glass andmy. invention maybe readily replaced and be free from in ury. It alsoprovides a substitute for expenslve glass lenses, will eliminate 1. Incombination'with an electric incandescent lamp, of a shade adapted to bespring fitted around the bulb of the lamp, a segmental opening therein,a multi-colored light emitting medium thereover, and spring means forholding the multi-colored medium over said opening.

2. In combination with an electric lamp, a halt shade or shell therefor,double spring means for holding the same to the lamp, an openin on theshade and over said lamp adapte to direct the rays upwards and at anangle, light transmitting means over said "opening, means on said halfshade for kee ing the lamp from direct contact therewith, and a discformed from the shade adapted to cover the endu-g the lamp for throwingthe rays below a horizontal line from the centre of the lamp.

In combination with an electric lamp and its reflector, of a shadeadapted to be secured to two portions thereof, spring means for both ofsaid parts, an opening in said shade, and a colored light emittingmedium for casting a glow upon said reflector of approximately acrescent shape.

4:. A headlight and in combination with its lamp and reflector, of ashade for the lamp having means for directing White rays downwards andsideways. an opening in the shade, a double colored glass cover for saidopening adapted to emit colored rays up-.

wards, at an angle and upon a part of said reflector, and spring holdingmeans for the shade positioned at the end and under said lamp. 7

In testimony whereof I have hereunto affixed my signature.

DANIEL G. DOZIEB.
